1. A power system comprising:

  • a first power converter and a second power converter;

    a first battery having a time to end of discharge (EOD) and coupled to output a current to the first power converter;

    a second battery having a time to EOD and coupled to output a current to the second power converter; and

    a control circuit coupled to the first power converter and the second power converter, the control circuit configured to monitor the time to EOD of the first battery and the time to EOD of the second battery, and in response to the time to EOD of the first battery and the time to EOD of the second battery not being substantially equal, control the first power converter to adjust the current drawn from the first battery to change a rate of decrease of the time to EOD of the first battery.
